Do you need a permit to build a fence in Southeast Louisiana? The answer depends on your parish, your property, and the type of fence you are installing. Getting it wrong can mean fines, forced removal, or a failed home sale inspection years down the line. This guide covers what homeowners across the Northshore and Southshore need to know before the first post goes in the ground.
Why Fence Permits Exist in Louisiana
Fence permits are not bureaucratic busywork. In Southeast Louisiana, they serve a practical function that goes beyond what most states deal with. The region sits in one of the most complex regulatory environments in the country for residential construction. Active flood plains, FEMA-designated special flood hazard areas, coastal zone management boundaries, and parish-level zoning codes all overlap in ways that affect what you can build and where.
A permit review catches problems before they become expensive. A fence built too close to a drainage servitude can block water flow and create flooding liability. A fence that crosses a property line — even by a few inches — can trigger a legal dispute that clouds the title. A fence in a historic district that does not meet design standards can result in a mandatory tear-down.
The consequences of skipping a permit are real. Parish code enforcement offices conduct proactive inspections in many areas, and neighbor complaints frequently trigger them. Unpermitted fences discovered during a home sale must either be permitted retroactively or removed before closing. Retroactive permits, when available at all, typically cost more than the original permit would have.
When a Permit Is Required
Most parishes in Southeast Louisiana require a permit for any fence over a certain height, any fence installed in a front yard, or any fence within a certain distance of a road right-of-way. The exemption thresholds vary by parish and municipality, but a general framework applies across most of the region.
Permits are typically required when a fence exceeds 4 feet in a front yard, exceeds 6 feet anywhere on the property, is installed within a flood zone or coastal zone, is part of a pool enclosure, or is being installed on commercially zoned property. Pool fences carry their own mandatory requirements under Louisiana state law.
Permits are typically not required for agricultural fencing on rural parcels, low decorative fencing under 4 feet in rear and side yards in some parishes, and temporary construction fencing. Always verify with your specific parish building department before assuming you are exempt.
Northshore Parish Requirements
St. Tammany Parish (Covington, Mandeville, Slidell, Madisonville, Abita Springs) — The St. Tammany Parish Building Department requires permits for most residential fences in incorporated areas. Height limits in residential zones are generally 4 feet in front yards and 6 feet in rear and side yards. Properties in FEMA flood zones require additional review to ensure fences do not impede flood flows. Covington and Mandeville have their own municipal codes that may impose stricter setback requirements than the parish baseline.
Tangipahoa Parish (Hammond, Ponchatoula, Amite City) — Tangipahoa Parish is more permissive than St. Tammany on residential fencing, but permits are still required for fences over 6 feet and for any fence on commercially zoned property. Hammond has its own permitting office with requirements that can differ from unincorporated parish rules. Agricultural fencing on rural land is generally exempt.
Washington Parish (Bogalusa, Franklinton) — Washington Parish is generally more permissive on residential fencing in rural and semi-rural areas. Franklinton has its own municipal permitting for in-town properties. Agricultural fencing is broadly exempt.
Southshore Parish Requirements
Jefferson Parish (Metairie, Kenner, Gretna, Harvey, Marrero) — Jefferson Parish has some of the most detailed fence regulations in the region. Residential height limits are 3.5 feet in front yards and 6 feet in side and rear yards. Permits are required for any fence in a front yard regardless of height. Significant portions of the parish lie within FEMA special flood hazard areas, and fences in those zones require additional review.
Orleans Parish (New Orleans) — New Orleans fence permitting runs through the Department of Safety and Permits. The city actively enforces its regulations, particularly in historic districts. In locally designated historic districts — covering large portions of Uptown, the Garden District, and the French Quarter — fence design, materials, and height are subject to review by the Historic District Landmarks Commission. Front yard fences are generally limited to 4 feet. Rear yard fences may go to 7 feet in some zones.
St. Charles Parish (Destrehan, Luling) — St. Charles Parish requires permits for fences over 6 feet and for fences in front yards in most residential zones. The parish actively enforces drainage servitude rules. Fences cannot be placed within parish drainage servitudes without prior approval.
Flood Zones and Fence Permits
This issue catches the most Southeast Louisiana homeowners off guard. A significant portion of residential land in this region sits in FEMA-designated Special Flood Hazard Areas (SFHAs) — shown on Flood Insurance Rate Maps as Zone A, AE, VE, or similar designations. If your property is in one of these zones, your permit review includes an additional layer of analysis that does not exist in non-flood areas.
The core concern is flow conveyance. Solid fences — wood privacy fences, vinyl privacy fences, solid masonry walls — can act as barriers to floodwater and cause water to back up onto neighboring properties. Because of this, most Louisiana parish floodplain regulations restrict solid fence materials in SFHAs. Open designs that allow water to pass through — such as chain link, wrought iron, aluminum, or open-rail wood — are typically required instead.
You can check your flood zone status using FEMA’s Flood Map Service Center at msc.fema.gov. Enter your address to see the current FIRM designation for your parcel. If you are in Zone AE or higher, plan for flood zone review as part of your permit application.
For flood zone properties, Tony’s Fencing recommends chain link and ornamental iron. Both options meet open-flow requirements while still providing security and defined property boundaries.
Pool Fences: Required Under Louisiana State Law
Pool fences fall under their own category in Louisiana law. Louisiana Revised Statute 40:1580.1 requires all residential swimming pools to be enclosed by a barrier meeting specific standards. The barrier must stand at least 48 inches high. It must have no openings that a 4-inch sphere can pass through. Gates must be self-closing and self-latching, and no door of the dwelling can provide direct access to the pool area without a barrier or alarm.
These requirements apply statewide regardless of parish, and permits for pool enclosure fencing are mandatory. If you are installing or replacing a pool fence, it will be inspected for compliance with the state barrier law. Tony’s Fencing installs pool aluminum fencing designed to meet Louisiana’s pool enclosure requirements. Details are available at tonysfencingandiron.com/custom-pool-aluminum-fencing/.
How to Apply for a Fence Permit
Start by contacting your parish or municipal building department. Most now have websites with permit applications available for download or online submission. You will typically need a site plan showing your property lines, the location of the proposed fence, the height and material, and the location of any gates.
Most residential fence permits in Southeast Louisiana cost between $50 and $150. Fees vary by parish and by the linear footage being installed. Jefferson Parish and Orleans Parish tend to be on the higher end. Processing times range from a few business days in smaller parishes to two to three weeks in larger ones. Properties in flood zones or historic districts should plan for additional review time.
Before You Apply: Get Your Survey
Pull your property survey before submitting any permit application. Many rejections and neighbor disputes stem from homeowners not knowing exactly where their property lines are. A current survey from a licensed Louisiana land surveyor eliminates that uncertainty and speeds up the process considerably.

What Happens If You Skip the Permit
Code enforcement in Southeast Louisiana ranges from reactive to proactive depending on the parish. Either way, the consequences of getting caught are consistent. A stop-work order halts construction immediately. Retroactive permits require inspection of the installed fence and may require modifications to bring it into compliance. Fines can reach several hundred dollars per violation, and significant code violations can result in a mandatory removal order.
The home sale scenario catches homeowners most off guard. During due diligence, buyers’ inspectors routinely flag unpermitted structures. An unpermitted fence can hold up a closing, reduce the sale price, or require removal as a condition of sale. The permit fee looks very different in that context.
Frequently Asked Questions: Fence Permits in Southeast Louisiana
Do you need a permit to put up a fence in Louisiana?
In most Southeast Louisiana parishes, yes. Permits are required for fences over 4 feet in front yards, fences over 6 feet anywhere on the property, fences in FEMA flood zones, and all pool enclosure fencing. Requirements vary by parish. The safest approach is to contact your parish building department before installation begins.
How much does a fence permit cost in Southeast Louisiana?
Most residential fence permits cost between $50 and $150. Fees vary by parish and by linear footage. Jefferson Parish and Orleans Parish tend to be on the higher end. Retroactive permits typically cost more and may require modifications to bring the fence into compliance.
Can you build a fence in a flood zone in Louisiana?
Yes, but with restrictions. Properties in FEMA Special Flood Hazard Areas are typically required to use open fence designs — such as chain link, ornamental iron, or aluminum — that allow floodwater to pass through. Solid wood and vinyl privacy fences may not be permitted in flood zones without special approval.
What happens if you build a fence without a permit in Louisiana?
Building without a required permit can result in stop-work orders, fines, and a requirement to obtain a retroactive permit or remove the fence. Unpermitted fences also create problems during home sales. Buyers’ inspectors routinely flag them, and they can delay or kill a closing.
